Ah well, the reason I want to update is because I'm getting "Error Loading Action: Init" errors.
One day everything is fine, the next I get hundreds of them, and the main problem is that I can't identify the FSM or templates they refer to, only the action.
I've spent all weekend exchanging that action for an alternative, to only get errors now with the new action name.
So, I don't think the problem is with the actions themselves, but how PM is working, storing meta data or whatever it is doing (I'm not a coder and have no idea).
But one common thing I've seen on other threads related to this issue, is that most users are on 1.9.0, just as I. That's why I want to update, and I'd actually just update to version 1.9.1 to try, but the Asset Store SUCKS and it only lets you download the latest version.
Anyway, I'm ranting. The thing is, if I still have bugged actions that will be a minor problem. I just want to update the core and see if it solves the problem.
Is that possible? Of course, I'd later on update the actions incrementally and very carefully.
